Inner Tube Question

I've got a 2007 Dyna Wide Glide and I'm swapping new tires onto it this season. Front 90/90-21 and rear 160/70-17.

I'm having trouble deciding which inner tube to use for my front tire. I've found two tubes, one is listed as 3.25"-3.5", and the other is listed as 4"-4.10". For context my tire is 3.5" wide, so the first option is the correct size right?

The guy at the parts counter said I should use the larger 4"-4.10" tube and not inflate it as much as oppose to pumping the smaller tube up to the max size. I can't decide if this is valuable advice or not.

Any input is welcome! Thanks.
